Before you ask, no it is not intended to make your titan fly, it is simply a tool used to accelerate your titan to much greater speeds. This component (should) fit quite nicely onto the carapace mount of your 'reaper' titan & is designed for melee builds.
:P - you'll need to figure that out for yourself depending on your printer.
Liek titans, so do I, that's why I'm here, to design more parts for warhammer titans. I also sometimes do knight parts. If you have any suggestions feel free to ask me in the messages thingy.
